SYSTEMS AND METHODS FOR LIDAR MEASUREMENT WITH REDUCED PEAK-FITTING BIAS

A LIDAR sensor system includes one or more processors. The processors transmit a signal to an environment of the LIDAR sensor system, receive, from an object in the environment, a return signal in response to transmitting the signal, determine correlation data between the signal and the return signal, identify, in the correlation data, an initial location of a peak, convolve the correlation data with a predetermined function to refine the initial location of the peak, and in response to the refined location of the peak, determine at least one of a distance to the object from the LIDAR sensor system or a velocity of the object.
